“We are running a small test, which shows the text ‘[Satire]’ in front of links to satirical articles in the related articles unit in News Feed,” a Facebook spokeswoman told MarketWatch. “This is because we received feedback that people wanted a clearer way to distinguish satirical articles from others in these units.”

While this particular tag isn't guaranteed to pop up in your News Feed any time soon, it does reek of an effort to cater to the lowest common denominator of Facebook users. Then again -- not all satire sites are as skilled (or well intentioned) as The Onion or its BuzzFeed-esque offshoot, ClickHole.

What do you think of a potential satire tag? Is it necessary? Is it censorship? Let us know your opinion.
